.s claims. (ci. ais-s) The invention aims to provide a simple, light.'

inexpensive and eiiicient lime spreader which may be readily attached tothe frame of a dump truck in position to receive the lime from the truck body when the latter isin dumping position and4 the usual gate of said body is opened sufiiciently to allow the lime to gravitate into the hopper of Instead of being equipped with ground wheels for driving the spreading, feeding and agitating means, the improved spreader is supported solely by the usual chassis frame of the truck and is operatively connected with'a drivenl part of said truck to beactuated thereby. This part is preferably a power take-off shaft of the truck transmission, which part customarily rotates in the same direction whether the truck be i idling, proceeding forwardly, or traveling rearwardly. Thus, the spreading disks of the spreader v -,take-olli shaft S which is utilized to drive the may be driven in the vsame direction and the truckdriven either forwardly or rearwardly as Y I the tubular housing I1 and may be secured to an may be most advantageous. v'

appropriate bracket 2I which is rigidly fastened vFigure 1 of the accompanying drawings is a side elevationof the spreader attached to the truck and operatively-connected with a power take-off shaft of the transmission. I

The structure disclosed in the drawings will be rather specifically described with the understanding, however, that within the scope of the invention as Vclaimedfminor variations may be made. Furthermore, lwhile the device is intended principally 'for' spreadinglime, it is obvious that it is notrestricted to this particular 'field of use.

A motor truckT .isshown having -the usual and the transmission ofthe truck includes a power spreading means and the lime-agitating and f eeding means.

AV horizontally elongated hopper 8 is disposed at the -rear end of the frame Fin position to refceive the lime from the body B when the latter is tilted to'inclined position andv the usual gate opened to allow the lime to slide into said hopper. In attaching the hopper 6 to the frame. F, 1 secure vertical angle bars 1 to therear end bar of theframe and secure angle plates 8 to the frontl wall 9 of said hopper, said angle bars 1 being provided `with rearwardly projecting flanges I which are overlapped by the angle' plates 8, said gether by bolts or the like I I.

anges and plates being detachably secured to- The hopper front wall 9 and the back wall I2 converge downwardly and are both inclined as shown, and the hopper bottom I3 is provided with forwardly declined discharge spouts I4 having in'- dividually adjustable gates or valves I for controlling the discharge of lime therefrom and' allowing only one or both of said spouts to function, as may be desired. Levers I8 may well he provided for operating the gates orvalves I5.

A tubularshaft housing I1 extends longitudinally under the hopper bottom I3 andis rigidly mounted in the angle between the front wall 9 and the forwardly declined spouts I4, said housing I1 being provided withoneenlarger'nent. I8

disposed between the spouts I4, and with two other enlargements I9 and 28 disposed Vbetween said spouts I4 and the ends of the hopper. The'enlargement may well be dispased'at one end of to the hopper 6, thereby rigidly supporting one end of the housing. The otherend of this-hous ing is suitably secured at 22 to a hopper-carried otherwise secured to the spouts- I4.

Two diskcarrying shafts 24 enlargements I9 and 20 respectively, the lower ends of said shafts 24 and 25 being provided with spreading disks 28 and 28 respectively, these disks being so related with the spouts I4 that the latter deliver the lime upon the inner portions'of saidv disks as shown, said disks being `drlven in opposite directions and serving to evenly spread the lime over the ground.

A main shaft 30 is mounted longitudinally in the tubular housing I1, said shaft being connected by gearing 3 I in the housing enlargement I8, with the shaft 24, and being similarly connected by and 25 pass I through bearings 26 and 21 on the bottoms of the gearing 32 in the housing enlargement 20, with the -45 shaft 25. AThe housing enlargement I8 contains l gearing 33 operatively connecting the 'shaft 30 with a drive shaft 34 whose front end is connected with the shaft S above described. The shaft 34 may consist of sections connected by universal joints 35, and maybe mounted upon the frame F by means of one or more bearings 364. The rear end of this sha-ft is rotatably mounted in an appropriate bearing 31 carried by the housing enlargement I8.

An additional shaft 38 extends within the lower portion of the hopper 6 and is mounted in appropriate bearings 39, said shaft being provided with worms 40 for feeding the lime from thevends of the hopper to the spouts I4, and being provided with additional worms 4I for feeding the lime from the center of said hopper'l to said spouts. The shaft 38 is also preferably equipped with agitating fingers 42 disposed directly over the spouts I4. One end of the shaft 38 projects beyond one end of the hopper 6 into a small housing 43 secured to said `hopper end,

which is also true of the shaft 30, and the two shaft ends are operatively connected by a chain 44 and .sprockets 45.

The shaft 34 drives the shaft 30 by means of the gearing 33, and said shaft 30 drives "the carrying shafts 24 and 25 of the disks ,28 and 29,

by means of the gearing 3| and 32 respectively.

Shaft 3|) also drives the lime-feeding and agitating shaft 38 through the instrumentality of the sprocket chain 44 and sprockets 45. Thus, the lime discharged into the hopper 6 will be effectively distributed in said hopper, discharged through the spouts I4 (or only one of them if desired) andv effectively spread by the disks 28 and 29' (or by only one if desired). The attachthe truck be driven forwardly or rearwardly, as

frame;

previously explained, proper spreading .will be accomplished regardless of the direction in which the truck be propelled, it being more desirable under certain conditions to spread while backing the truck, and more desirable under other conditions to spread while driving forwardly.

While excellent results may be obtained with the structure shown and described, attention is again invited to the possibility of making varia'- tions within the scope of the invention as lclaimed.

. I claim:-

1. In combination with a motor truck having a chassis frame and a dump body over said a horizontally elongated hopper disposed' transverselybehind said frame in-position to receive material discharged from said dump body, angle bars secured to the rear end of said frame and having rearwardly projecting flanges disposed in parallel vertical planes, forwardly projecting angle plates secured to the front side of said hopper in parallel vertical planes and overlapping said flanges, bolts securing said angle plates to said flanges, means for spreading the materialdischarged from said hopper, and driving means operatively connecting said spreading means with a driven part of the truck.
